Conditioning particulate substrate structure and method for conditioning particulate substrate.

摘要

A particulate substrate comprising a particulate base (2) serving as a growing medium including growing vegetable matter (3) in a surface layer (L) thereof, an upper anode (6) comprising an electrokinetic geosynthetic generally plane disposed generally horizontally within the particulate base (2) to be placed on a surface layer thereof (L) in the vicinity of the roots (5) of the growing vegetable matter (3), a lower cathode ( 8) disposed within the particulate base 82) generally below and parallel to the anode (6), means for connecting a power source (11) between the anode (6) and cathode (8) to apply a potential difference between them to direct an electro-osmotic process and thus to alter the moisture level in the vicinity of the anode and further to generate oxygen at the anode, control the pressure of pore water and decompress the cap a surface of the particulate.
